摘　　要：随着高速公路建设逐渐向地质环境复杂的山区延伸,地质选线方法已成公路建设领域亟待解决的关键技术问题。现有的方法主要针对具体工程特点提出原则性解决方案,缺乏通用性的定量分析模型。在分析文献与案例的基础上,提出地形地貌、地层岩性、地质构造、水文地质、环境地质、地震与新构造运动、不良地质和特殊岩土等8个影响因子,构建层次分析、模糊综合评价模型。基于地质调绘、地质勘察,遥感影像等原始资料,借助ArcMap软件的空间与属性分析功能,将地质影响因子分离,并分级量化。运用层次分析、模糊综合评价法对格栅数据进行加权叠加、模糊逻辑运算,形成格栅综合成本。基于Dijikstra算法原理,综合运用ArcMap内嵌距离成本分析、成本路径分析工具,实现全面考虑工程地质影响的最佳线路选择。将所建模型运用于新建G0711高速公路乌尉段线路走向选择,取得良好的效果。With the highway construction gradually extending to the mountainous area with complex geological environment,the geological route selection method has become the key technical problem to be solved in the field of highway construction.The existing methods mainly put forward the principle solutions according to the specific engineering characteristics,and lack the general quantitative analysis model.Based on the analysis of literature and cases,in the paper eight influencing factors are put forward,including topography and geomorphology,stratum lithology,geological structure,hydro-geology,environmental geology,earthquake and neotectonic movement,unfavorable geology and special rock and soil,and the analytic hierarchy process(AHP)and fuzzy comprehensive evaluation model are established.Based on the geological mapping,geological survey,remote sensing image and other original data,with the assistance of the spatial and attribute analysis function of ArcMap,the geological impact factors are separated and then classified and quantified.AHP and fuzzy comprehensive evaluation method are used to carry out weighted superposition and fuzzy logic operation on grid data to form comprehensive cost of grid.Based on the principle of Dijikstra algorithm,the ArcMap embedded distance cost analysis and cost path analysis tools are used to realize the best route selection considering the engineering geological impact.The model is applied to the route selection of Urumqi-Yuli section of the newly built G0711Expressway,which has obtained good results.
